Bruno Zumino (April 28, 1923, Rome, Italy) is an Italian theoretical physicist and emeritus faculty at the University of California, Berkeley. He obtained his DSc degree from the University of Rome in 1945.
Bruno is well-known for his proof of the CPT theorem in collaboration with Gerhart Luders. He pioneered systematization of the effective chiral Lagrangians. In collaboration with Julius Wess, they invented the so-called "Wess-Zumino model", which is widely viewed as the first four dimensional supersymmetric quantum field theory. He initiated the field of supersymmetric radiative restrictions. He is known for his deciphering of the structured flavor-chiral anomalies which is codified in the Wess-Zumino-Witten model of conformal field theory.
